Description

Technical Field

[0001] This utility model relates to the technical field of groundwater extraction equipment, and specifically to a groundwater extraction device. Background Technology

[0002] Groundwater refers to water that is buried below the Earth's surface and exists in soil pores or rock fissures. It is an important component of the Earth's water cycle, mainly originating from atmospheric precipitation, surface water (such as rivers and lakes) seeping into the ground, and some water released from deep underground rocks. Generally, extraction devices are needed to extract groundwater.

[0003] Chinese patent CN116020196A discloses a groundwater extraction device capable of filtering sediment, including an installation platform. The top of the installation platform has an installation hole, and an installation pipe is slidably connected within the installation hole. This groundwater extraction device uses a first water pump to draw water. As the water flows, it drives a transmission mechanism in a first filtration mechanism to rotate. The transmission mechanism cleans the inner surface of the first filter plate on the filter pipe. Simultaneously, the transmission mechanism drives a first permanent magnet, an installation box, and a first cleaning plate to rotate. The first cleaning plate drives a first brush to rotate. Furthermore, through the cooperation of a second permanent magnet and an arched magnet, the outer surface of the first filter plate is cleaned by a rotating and reciprocating brushing motion.

[0004] Existing extraction devices typically have a filter at the inlet to pre-filter groundwater. However, because the filter is deep underground, it is difficult to clean. Over time, impurities clog the filter, reducing the pumping efficiency of the groundwater extraction device. In addition, most existing extraction devices can only extract groundwater and cannot replenish it, resulting in slow recovery of the groundwater level and impacting the ecological environment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] like Figure 1-4 As shown, the groundwater extraction device described in this embodiment includes a fixed base 1 with mounting holes 13; a bidirectional water pump 2, which is located on the upper part of the fixed base 1; a pumping pipe 3, which is located at the input end of the bidirectional water pump 2, and a filter cover 5 is provided at the lower end of the pumping pipe 3; an outlet pipe 4, which is located at the output end of the bidirectional water pump 2; and a three-way valve 6, which is located at the end of the outlet pipe 4 away from the bidirectional water pump 2. One end of the three-way valve 6 is provided with a purification component, and the other end is provided with a rainwater collection component. The rainwater collection component is used to collect rainwater to replenish the groundwater level. During the replenishment process, the water flow backwashes and cleans the impurities on the filter cover 5. By setting up the rainwater collection component, the clogging of the filter cover 5 is effectively reduced, the pumping efficiency of the bidirectional water pump 2 is ensured, groundwater is replenished, and environmental protection is strengthened.

[0027] The purification assembly includes a purification pipe 7 and a purifier 9. One end of the purification pipe 7 is connected to a three-way valve 6. The purifier 9 is mounted on the purification pipe 7. The purification pipe 7 is also equipped with a first valve 10. The purifier 9 includes a housing 91 and a filter screen 94. The filter screen 94 is located inside the housing 91. One end of the housing 91 has an inlet 92, and the other end has an outlet 93. The interior of the housing 91 is filled with activated carbon 95, which is located at the end of the filter screen 94 near the outlet 93. The purification assembly is used to perform secondary filtration on the extracted groundwater, effectively improving the cleanliness of the groundwater and ensuring water safety.

[0028] The rainwater collection assembly includes a rainwater pipe 8 and a collection cover 12. One end of the rainwater pipe 8 is connected to a three-way valve 6, and the other end is connected to the collection cover 12. A second valve 11 is provided on the rainwater pipe 8, and the collection cover 12 is shaped like a conical hat.

[0029] Working principle

[0030] When extracting groundwater, the first valve 10 is opened and the second valve 11 is closed. Then the bidirectional water pump 2 is started. After the groundwater is initially purified by the filter cover 5, it flows sequentially through the pumping pipe 3, the bidirectional water pump 2, the outlet pipe 4, the first valve 10 and the purification pipe 7 into the purifier 9, thus completing the extraction and purification of groundwater.

[0031] When replenishing groundwater, open the second valve 11 and close the first valve 10, and rotate the bidirectional water pump 2 in the opposite direction. The rainwater in the collection cover 12 flows through the rainwater pipe 8, the second valve 11, the outlet pipe 4, and the bidirectional water pump 2 into the pumping pipe 3, and then is output from the lower end of the pumping pipe 3 to backwash the impurities on the filter cover 5 and replenish the groundwater.
